Specification of Letters Patent.

Patented Dec. Ill, Twit? Application filed. April 3, 1917. Serial No. 159,452.

To all whom it may concern:

Be it known that I, RAYMOND O. WONES, a citizen of the United States, residing at Maplewood. in the county of Shelby and State of Ohio, have invented certain new and useful Improvements in EnginePrimers, of which the following is a specification.

This invention relates to an improvement in engine primers and more particularly to a device of this character intended to be permanently installed for use in conjunction with an automobile engine, a marine engine, or other type of internal combustion or explosive motor, it being a purpose of my invention to provide a structurewhich may be permanently installed with the engine at the factories or which may be manufactured and sold as an accessory to be applied and connected by the individual user.

A further object is to provide a device of the character described which is of such construction that air and gasolene or other volatile liquid will be taken separately, conducted to a mixing chamber, and then after being mixed in the chamber will be supplied under pressure and in the form of an explosive charge directly into the cylinder or cylinders of the engine with which the device is fitted for use.

Yet another object is to so construct the parts that a connection may be established directly to the gasolene line throu rh the carbureter, and the quantity of gaso lene taken therethrough, as well as the quantity of air introduced into the explosive charge can be varied and regulated.

With the above and other objects in View, which will be in part understood and in part apparent from the specification, drawing, and claims, my invention consists in certain novel features of construction and combinations of parts which will be hereinafter more fully set forth.

In the drawing:

Figure 1 is a view somewhat diagrammatically illustrating the parts and the manner of connecting the same with an engine of the multiple cylinder type;

Fig. 2 is a detail view showing a slightly modified form of construction for the pressure pump; and

Fig. 3 is a fragmentary sectional view to disclose one form of gasolene and air supply control valve which might be employed.

A pump 1 which is of the ordinary plunger type has the plunger rod terminating in a handle 2 which is accessible from the exterior and by withdrawing the plunger rod from the cylinder and again forcing it into the cylinder through the medium of the handle 2, a suction and pressure stroke will be accomplished. A gasolene supply pipe 3 is connected from the carburcter line 4 to the cylinder of the pump 1, a. check valve 5 hoW- ever being mounted in the gasolene supply pipe to check against back flow of gasolene from the cylinder of the pump 1 to the carbureter line l. A combined air and gasolene supply line 6 is connected with the cylinder of the pump 1 and then at its free end has connection with a mixing chamber 7, a check valve 8 being mounted in the line 6' to check against back flow into the cylinder of the pump.

The device of my invention is adapted for application to a single cylinder or a mult1ple cylinder engine, and itis a purpose to have a supply line to each of the engine cylinders, which supply line will open into the combustion chamber. With this purpose. in view, the prime cocks of the cylinders might be removed, provided the engine has prime cocks fitted therewith, or in absence of such prime cocks, prime plugs could be employed. The mixing chamber 7 has the charge supply pipes 9 connected therewith and extended to communicate with the various cylinders of the engines through the connections 10 which will be established through the holes left by removal of the prime cocks or will be connected directly with the prime cups of the prime plugs employed for the fitting of the device of my invention. Each of these charge supply pipes 9 has a check valve 11 connected therein adjacent the mixing chamber 7 and thus back firing into the mixing chamber 7 from the ignition of the explosive charge is checked. \Vith the structure as described. the handle 2 on the pump plunger can be grasped and moved to cause alternate suction and pressure strokes of the piston or plunger within the cylinder of the pump, and by reason of the fact that the check valves 5 and 8 are mounted to Work alternately, the valve 5 being an intake valve whereas the valve 8 is an outlet check, gasolene from the carbureter line 4 will be sucked through the pipe 3 and will then be forced through the pipe 6 to the mixing chamber 7 from whence it will be supplied under pressure through the charge supply pipes 9, however,'rather than depend upon air already valve is turned through manipulation of the handle 14, a straight passage through the pipe 3 will be accomplished in one setting whereas communication to the atmosphere through the port 15 will be established in a second setting. By provision of the valve 12, the handle 14 can be set to establish straight communication through the gasolene supply pipe 3 and then the handle 2 may be grasped and the plunger moved upwardly to suck or draw gasolene through the pipe 3 into the cylinder of the pump, the valve 5 checking against back flow and the valve 8 being opened by the instroke of the plunger to permit passage of the gasolene through the pipe 6 to the mixing chamber 7. The handle 14 is then turned to swing the plug 13 to establish communication through the port 15 to the atmosphere and the plunger is again drawn outwardly within the cylinder of the pump, this suction stroke acting to take air in through the port 15 into the cylinder of the pump and the down stroke of the plunger forcing this air through the pipe 16 to mingle with and gas ify the volatile liquid as contained in the mixing chamber 7 and also supplying pressure to flow the explosive charge thus formed through the supply pipes 9 and through the connections established with the cylinders directly into the explosive chambers thereof.

As is shown in Fig. 2, the pump cylinder 16 might be set at an angle upon the dash of an automobile or upon some other suitable support and then perhaps the plunger might be manually manipulated with a little greater ease, and also it will be understood that the mixing chamber 7 could be mounted and supported in any desired arrangement although it is perhaps preferable that this chamber be made to assume the substantially conical shape as shown in Fig. 1 and that it be as nearly centrally located as practical so that the explosive mixture or charge will be supplied in uniform quantity to all of the explosive chambers.

While in the foregoing I have shown and described only certain specific adaptations and arrangements of the parts, it will of "course be understood that a number of changes and variations might be resorted to in the form and arrangement of parts as well as in the manner of constructing the various elements, and hence I do not wish to be limited to the exact disclosure but only to such points as may be set out in the claims.

I claim 1. An engine primer including a pump, a combined air and gasolene supply pipe connected with the pump and extended to be connected with the engine, a gasolene supply pipe leading from a suitable source of supply to the pump and provided with a check valve therein, and a two-way valve mounted in the gasolenc supply pipe to be manipulated to connect the pump with the gasolene supply and with the atmosphere.

2. An engine primer including a mixing chamber, charge supply pipes connected from said mixing chamber to the cylinders of the engine, check valves mounted in said pipes to check against back fire into the mixing-chamber, a pump of the plunger type, a combined air and gasolene supply pipe connected from the pump cylinder to the mixing chamber and provided with a check valve checking against back flow into the pump cylinder,a gasolene supply pipe leading from a suitable source of supply to the pump cylinder and provided with a check valve therein, and a two-way valve mounted in the gasolene supply pipe to be manipulated to connect the pump with the gasolene supply and with the atmosphere.

3. An engine primer including a mixing chamber of substantially conical form, a plurality of explosive mixture carrying pipes connected with the cylinders of an internal combustion engine and at their free ends connected with the mixing chamber, check valves mounted in said pipes to guard against back fire, a pump of the plunger type adapted to intake and exhaust on alternate strokes, a combined gasolene and air supply pipe connected with the upper part of said mixing chamber and at its free end with the cylinder of the pump, an outlet check valve mounted in said pipe, a gasolene supply pipe connected with the carbureter'line and with the pump cylinder and having an intake check valve connected therein and a two-way valve mounted in said gasolene supply pipe to be set to open communication to the pipe and to establish communication to the atmosphere.

In testimony whereof I aiiix my signature in presence of two witnesses.
